The case file

What happened

Arif Raihan Dwip was a third-year mechanical engineering student at the Bangladesh University of Engineering and Technology (BUET), where he lived in Nazrul Islam Hall. He was a convenor committee member of the Bangladesh Chhatra League and had participated in the Shahbagh movement, which supported the trial of individuals accused of war crimes during the Bangladesh Liberation War. Dwip had been accused of verbally abusing an imam at a University of Dhaka mosque for supplying food to a Bangladesh Hefajat-e Islam rally on 5 April 2013. Following this, threats against him appeared on a Facebook group called "Buetian."

On 9 April 2013, Dwip was stabbed inside Nazrul Islam Hall at BUET. He was treated by neurosurgeon Pijush Kanti Mitra at Dhaka Medical College Hospital before being transferred to Square Hospital. He died at Square Hospital at 3:30 am on 2 July 2013. The Bangladesh Chhatra League attributed the attack to Bangladesh Jamaat-e-Islami and its student wing, Islami Chhatra Shibir.

In the aftermath, Dwip's brother filed a case, leading to the arrest of a fellow BUET student, Mezbah Uddin, who was a fourth-year student detained from Dr MA Rashid Hall. According to detectives, Mezbah Uddin confessed and stated he had been influenced by a radical preacher, and had been in communication with Mufti Jasimuddin Rahmani. He was later released on bail, and the trial did not proceed further. BUET formed a three-member investigation committee, and students boycotted classes to demand punishment for those responsible, submitting demands to vice-chancellor S. M. Nazrul Islam. Classes resumed on 21 April 2013 after the Bangladesh government said it would form its own Ministry of Home Affairs investigation committee.

Dwip's father, Sk Ali Azam, sought the intervention of Prime Minister Sheikh Hasina in pursuing the case. Separately, another BUET student and Gonojagoron Mancho activist, Tonmoy Ahmed Moon, was stabbed on 12 August 2013 in Gaibandha District, reportedly by Bangladesh Islami Chhatra Shibir activists.

On 2 July 2024, Dwip's death anniversary was marked at BUET, with friends and family expressing resentment over the continued lack of a verdict in the case. They alleged that Bangladesh Islami Chhatra Shibir, Basherkella, and Hizb ut-Tahrir Bangladesh had glorified the accused while branding Dwip an "enemy of Islam." In August 2024, Mufti Jasimuddin Rahmani was released on bail by the Bangladesh interim government led by Muhammad Yunus.
